Final report on link level and system level channel models - Winner

WINNER D5.4 v. 1.4
When comparing the shadow fading autocorrelation, we got the following results for the autocorrelations
of the over-all shadowing: For 2.45 GHz the correlation distance was approximately 330 m and for the
5.25 GHz it was approximately 320 m. Note that the route used for the comparison was the one with the
greatest correlation distance.
5.6.9.2 Rms-delay spread
The RMS delay spread is shown in the Table 5.46 for the centre-frequencies 2.45 and 5.25 GHz. The
difference is considerable. For 2.45 GHz the mean delay spread for LOS is 35 % and for NLOS 80 %
higher. Same trend can be found in the references cited in Section 5.5.
